Pizza Hut

If you were thinking dominoes might have been the largest pizza chain in the world, think again. Pizza Hut wins by a landslide with around 13,100 restaurants worldwide. 

As with the others, the International outlets get more creative with their toppings. For example: Egyptian stores offers crusts which can be stuffed with meatballs and cream cheese. Pakistani stores offer a version stuffed with spicy BBQ kabobs too.
